Invited Session: Energy Recovery
Maximizing Energy Recovery in Waste-to-Energy Plants (0.5 CEU)
Wednesday, September 27, 2017
9:35 – 10:05
Moderator: Dr. Efstratios Kalogirou, Chemical Engineer, Greece
The future energy system, with the expected wider use of intermittent power sources such as solar and wind, will demand very flexible base-loaded plants to compensate for wide load variations in the electrical grid. Waste-fired power plants are an ideal solution using domestic fuel with a positive impact on reducing greenhouse gases (GHG). High overall energy efficiency ensures maximum substitution of fossil fuels, thereby reducing the impact of GHG. The presentation will describe flue gas condensation as one way to increase energy efficiency and is used in modern combined heat and power (CHP) plants. A project for a waste-fired power plant in Sweden will be presented as a unique example of this technology. A new waste-fired power plant in Copenhagen will also be discussed, setting new standards in energy power efficiency when it goes into operation in 2017. The new facility is expected to increase the total energy efficiency by up to 20 percent compared to an existing facility at the site.
Following the presentation, participants will be able to understand the technologies available in a modern waste-to-energy facility to achieve maximum energy recovery.
